The former Heart DJ joined the BBC last year, and was rumoured to be the highest paid presenter at the station.
He initially hosted the breakfast show on his own, but was later joined by Dotty McLeod, who had hosted the show before.
Dotty will now present the Breakfast Show on her own once more.
A BBC spokesman said: “Kev Lawrence will be leaving BBC Radio Cambridgeshire’s breakfast show when his contract ends in July. During the Coronavirus pandemic the station is broadcasting a streamlined schedule and we are currently unable to renew Kev’s contract at this time. Dotty McLeod will return as the main host of weekday Breakfast, 6-10am.”
Station Editor David Harvey said, “I’d like to thank Kev for his tremendous contribution to our output over the last 12 months. We will be keeping in touch and I hope we can work together again in the future.”
